SPECIFICATION forming part of Letters Patent Bio-658,508, dated September 25, 1900.

Application filed April 30, 1900. Serial No. 14,936. (No model.)

To rtZZ whom it may concern:

Be it known that I, GEORGE O. REDPATH, a citizen of the United States, and a resident of Frankfort, in the county of Franklin and State of Kentucky, have invented a certain new and useful Improvement in Needles for Weaving Cane Fabrics, of which the following is a full, clear, and exact description, reference being had to the accompanying drawiugs, forming part of this specification.

My invention relates to a needle for weaving the diagonal strands into cane fabrics,and has for its object the production of a novel and efficient apparatus; and it consists in the novel features of construction hereinafter more fully described and claimed, the invention relating to that class of needles in which the pirn and the needle-shaft are made in two parts. Heretofore in needles of this construction it has been customary to provide the pirn with a hardenedsteel tip having a socket into which would take the pointed or tapering tip of the needle. As there is considerable friction and consequent wear at this point, it was found necessary to provide the pirn with a specially-hardened steel tip. In making the pirn and giving it spiralit-y it has been found preferable to use soft steel,

which, however, would not stand the consequent strain at the point where the needleshaft bears against the pirn, and the hard-A ened tip, with its receiving-socket, was secured to the pirn. It has been found in practice that the strains to which the pirn is subjected would cause the hardened tip to part from the body of the pirn, and thus prove very unsatisfactory. Furthermore, the needles as heretofore constructed were provided with the usual eye for the reception of the cane to be Woven into the fabric. As the needle is inserted or passed through the fabric by pressure it has often resulted in the breaking of the needle at the eye. It is to overcome these difficulties that I have designed my new and useful needle illustrated in the accompanying drawings, in which- Figure l is a plan View of a piece of foundation fabric with my improved needle. Fig. 2 shows a plan view of a part of the weavingneedle with my improvement. Fig. 3 is a plan view of the pirn. Fig. 4 is a plan view' of the pirn.-

Like letters of reference indicate identical through which the cane may be inserted. v

This link or stirrup?) is pivotally secured to the needle-shaft A in order that-it may re verse its position and adjust itself to the op eration or direction of the needle. By the use of the link or stirrup 1) instead of an eye the needle is made stronger at this point, as is readily understood. It has also been customary heretofore where the hearing was had in asocket in the pirn to provide the needle-shaftwith a hardened-steel tip or point, which was brazed or in any suitable manner secured to the needle-shaft, thus producing a needle-shaft made of two pieces, which is very apt to become broken at that point.

To guide the needle-shaft properly through and permit it to interweave itself with the warp and woof of the foundation fabric, I provide the pirn B, made of a spiral pitch to correspond with the meshes of the foundation fabric upon which it is to operate. This pirn Bis so formed that its rear portion is coincident with the axis of the spiral. At the rear end of the pirn Bit is provided with a steel pin 0. This pin 0 is adapted to be inserted in the small socket a in the forward end'of the needle-shaft A. (See Fig. 1.) As it greatly facilitates the manufacture of the pirn to be able to use a soft or mild steel for the spiral portion, the friction at the bearingpointwith the needle-shaftwould veryquickly Wear this point cuuless it were made of hardened steel. It Will be readily seen that this may be done and the point 0 inserted in the end of the pirn without weakening the structure at this point, as is the case with the constructions heretofore used.

In operation the point or pin a on the pirn B- is inserted inthe socket or recess a in the needle-shaft A. e The operator then inserts the front end of the pirn B in one of the meshes at the edge of the fabric and then grasps the needle-shaft A and moves or presses it forward diagonally, the pirn B being caused to rotate, which its pivotal connection with the needle-shaft permits, entering the successive meshes correctly It will thus bereadily understood that the pirn B guides the needleshaft A through the meshes of the fabric to be threaded and withdrawn, drawing the cane-strand diagonally into the fabric.

I have illustrated in the drawings aneedleshaft with the usual eye, though a stronger construction is bad when the needle is provided with a stirrup instead of an eye, which by reason of its pivotal connection with the needle-shaft will adjust itself according to the direction in which the needle-shaft is travcling.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A device of the character described comprising a single shaft with a socket at its tip, and a link or stirrup for the reception of the thread, and a pirn having a spiral advancing end and straight rear portion arranged to enter the socket in said shaft, substantially as and for the purpose described.

2. A weaving-needlehaving a long shaft and a link or stirrup pivotally secured to the shaft, said shaft providedwith a socket or recess in its tipcircnlai-in cross-section, in combination with a pirn having a spiral advancing end, and a straight rear portion arranged to enter the socket in said shaft, substantially as and for the purpose described.

3. A weaving-needle having a long shaft, and a link or stirrup pivot-ally secured thereto, said shaft provided with a socket or recess in its ti p circular in cross-section, in combination with a pirn having a spiral advancing end and astraight rear portion coincident with the axis of the spiral, said straight portion provided with a pin adapted to enter and have bearing in said shaft-recess to permit of the turning of the pirn independent of the shaft, substantially as and for the purpose de scribed.
